We regret to announce that we will be discontinuing Echofon for Mac in order to focus more on our mobile line of Echofon apps. The current version of the Mac desktop version will continue to function for those users that already have it installed, but unfortunately, there are no planned updates. We want to thank all of our Echofon for Mac users and while we deeply apologize that we will no longer be able to provide a great Twitter experience on Mac, we are committed to providing our users with a fantastic mobile experience on both iOS and Android! Please reach out to our support team with any questions/concerns.
